The dynamical spin structure factor S(q,ω) is obtained analytically for the one-dimensional supersymmetric t-J model with 1/r2 interaction. In contrast with the conventional view on the spin-charge separation, interpretation of S(q,ω) requires both fractionalized and non-fractionalized electrons depending on the energy-momentum region. At low energies, the spectrum is naturally explained in terms of spinons, holons, and antiholons, all of which obey fractional exclusion statistics.
